Hot rods crank

Hey guys I finally came up with the money to put my bike back together, and I'm not really sure what to do with the crank. What is the difference between the heavy duty crank and regular hot rods crank? I don't think I can afford to go with Falicon or any other of the name brands that are always recommended. I'm just at a loss now. Feeling pretty stupid. I'd also like to help support some of the sponsors of this site because I'm always reading tips and tricks from everyone on here. Sorry for the novel. But thanks for any input. By the way need cams, piston, crank, and cylinder. Any suggestions?

I'm going to have my crankshaft cryogenecly frozen to make it stronger. You might look into the same for your crankshaft, its suppose to make metal stronger, and my local dyno shop says it really works, and I think its not that expensive either. Just an idea

Well I guess hot rods has put the kfx450r crank on hold. Boo. Now I guess It's time for just a connecting rod with better bearings. A few local shops say they can rebuild my stock crank and true it within .001-.002" for 95 bucks in labor.

Yeah unfortunately you can't actually get the Hot Rods crank. I talked to somebody at KB and they were freaking awesome. Probably the most helpful of anyone I've ever talked to. I will for sure be buying my cams from them. I would get the connecting rod, but I don't want to just show up to my mechanic with the crank and rod. I know it sucks when people want to buy their own shit and have you install it. Now, should I go big bore or stock cylinder? Thinking over bore.

Did you ever figure out what you'd like to do? I wasn't able to find any cheaper crankshafts for you. Hopefully HotRod will release a crankshaft soon for the KFX450 that is dependable.
